摘要： An apparatus for forming a spirally wound stator core includes a pair of forming rollers having a wedge-shaped gap therebetween, a winding drum, a drum-drive motor, and a roller presser. A strip of magnetic material is inserted into the wedge-shaped gap to be pressed at a controlled pressure so that the strip is bent into a spiral with one side of the strip being radially inside. The controlled pressure is changed automatically according to a memorized relationship between the rotation speeds of the pair of forming rollers and suitable pressures applied to the strip.

摘要： A motor incorporates a rotor 21 incorporating a cylindrical magnet 24 which has segments magnetized at predetermined pitches in a circumferential direction thereof; and a stator 25 for imparting a rotating magnetic field to the magnet 24 so as to rotate the rotor 21. Each of the magnetized segments is magnetized such that the inner portion and the outer portion are magnetized to different polarities and the magnetized segments disposed at adjacent pitches are magnetized to opposite polarities. The stator 25 incorporates a first polar tooth row and a second polar tooth row each of which is constituted by polar teeth corresponding to the predetermined pitches of the magnetized segments such that the polar teeth disposed opposite to the magnetized segments across the magnet are magnetize to different polarities, and the polarities of the first polar tooth row and the second polar tooth row are switched so that a rotating magnetic field is imparted to the cylindrical magnet 24. In the embodiment, the first polar tooth row and the second polar tooth row consisting of polar teeth disposed opposite to one another cross the magnet 24 are composed of two pairs including one pair constituted by a core 26 and a stator cap 30 and one pair constituted by a core 27 and a stator cap 31.

摘要： There is provided an information display position-defining circuit comprising a local pulse oscillator reset by a horizontal synchronization pulse; a horizontal pulse counter which is reset by the horizontal synchronization pulse and counts an output pulse from the local pulse oscillator; a vertical pulse counter which is reset by a vertical synchronization pulse and counts the horizontal synchronization pulse; and a character position signal generator for issuing a signal denoting a character display position in response to output signals from the horizontal and vertical pulse counters. The circuit further includes a signal generator designed to selectively send forth a first signal having the same frequency and phase as the horizontal synchronization pulse and a second signal having the same frequency as the first signal, but having a phase different from a first signal; and a comparator for comparing the phases of an output signal from the signal generator and vertical synchronization pulse and, at the same time of synchronization between both phases, selecting the first or second signal.
